Broadcom says it won’t sell Qualcomm’s national security assets

Broadcom has promised not to sell critical national security assets to foreign buyers if its deal to buy chipmaker Qualcomm is approved, another effort by the Singapore-based firm to appease U.S. security concerns.

Separately, Qualcomm it discontinued the role of executive chairman and named a new non-executive chairman as it seeks to curry favor with shareholders ahead of a proxy fight with Broadcom now slated for April 5.

Broadcom’s $117 billion bid for Qualcomm has warped into a complex fight over regulatory approvals, security nerves about China’s influence on global mobile networks and the best way forward financially for one of the world’s dominant chipmakers.

In an open letter to the US Congress on Friday, Broadcom promised to invest $3 billion in research and engineering and $6 billion in manufacturing in the United States annually. It did not say how those numbers compared with current spending by the two companies.

The US government has raised concerns that Chinese companies, including the big network equipment and mobile phone maker Huawei Technologies, will take advantage of any openings to take the lead in the next generation mobile phone networks known as 5G.

“Broadcom will not sell any critical national security assets to any foreign companies,” the letter said. “Of course, any dispositions of assets to foreign buyers would be themselves subject to CFIUS review.”
